The Quantum Mechanics Solver is unique as it illustrates the application of quantum mechanical concepts to various fields of modern physics. It aims at encouraging the reader to apply quantum mechanics to research problems in fields such as molecular physics, condensed matter physics or laser physics.

This is an expression of desire to learn the ideas of modern theoretical physics and natural sciences as a whole. This is a view from the side at what is happening with science and human thought. This is a search of something, not simply imperceptible and being beyond understanding, but such that could explain causation of everything. New interpretation of paths followed by the modern physics, redefinition of the universal laws and doubts which are reinforced by the new revolutionary movements in science, lead to thought that all the tangled trails of research, by and large, - just a long way to nowhere.

Quantum mechanics is not simply a branch of physics or some direction in science. Quantum mechanics is a very different conception on the reality around us and about our place in the world. To understand what it means, here is an example of such idea: if two interrelated electron are divided by space as big as the universe, and we affect one of them, the second electron instantly react to changes with the first. This is not a signal between them - it is the relationship as a single whole system. If we bear in mind that the universe came from the one Big Bang, then reality surrounding us is a single entity, and everything we perceive is the design of this whole.
